I was just browsing free downloads from mozilla because their products are unbelievably useful and awesome in every way. I found one program called "Joost." On it, there are tons of channels, like the Discovery Channel and Comedy Central, and tons of TV shows like How I Met Your Mother and Ren and Stimpy, which I actually can't because it's too disgusting. I'm assuming joost is legal for various [and possibly very logical] reasons. Also, the interface is fun, but took me a second to get used to. Here are some cool screenshots.
